Jrain, a leading manufacturer of fiberglass-reinforced polymer (FRP) tanks and vessels, offers innovative field winding equipment for constructing large-scale FRP tanks in challenging environments. These field-manufactured tanks are designed to overcome size and logistical constraints, making them ideal for industries requiring corrosion-resistant storage solutions. This article explores the features, advantages, technical specifications, and applications of Jrain’s Large Size Field Tanks, alongside insights into the company’s expertise and adherence to international standards.

Product Features and Manufacturing Process

Jrain’s field winding equipment enables the on-site production of large FRP tanks with diameters ranging from DN4500mm to DN25000mm. The process involves several key steps:

1. Mobilization: A dedicated manufacturing team is dispatched to the project site, with a Project Manager overseeing operations.
2. Assembly: The winding machine and mold are set up according to the tank’s required diameter.
3. Construction: A liner is fabricated, followed by filament winding using resin and fiberglass tailored to the application’s needs.
4. Finishing: After demolding, the tank is placed in its designated location, and fittings such as nozzles, ladders, and handrails are installed. A hydrostatic test ensures structural integrity before handover.

The mechanical properties of laminates produced via field winding equipment are comparable to those manufactured in controlled workshop environments, ensuring durability and reliability. Jrain’s systems are designed to accommodate different resins and fiberglass grades, allowing customization for corrosive or abrasive liquids and gases. This flexibility makes their tanks suitable for chemical processing, water treatment, and industrial storage applications.

Key Advantages of Field Manufacturing

On-site production of FRP tanks offers several cost-effective and practical benefits:

• Reduced Transportation Costs: Large tanks are often too cumbersome to transport, making field manufacturing a more economical choice.
• Flexibility: Customization to site-specific conditions and regulatory requirements ensures optimal performance.
• Coordination: Seamless integration with other on-site contractors streamlines project timelines.
• Quality Control: Jrain’s equipment ensures consistent laminates that meet ASME RTP-1, ASTM D3299, and BS EN 13121 standards.

Additionally, Jrain provides training to customers on machine operation and maintenance, ensuring long-term usability of the field winding equipment. This support is critical for industries operating in remote or harsh environments where technical expertise may be limited.
